BACKGROUND

The present disclosure relates to a connecting device and a notebookcomputer, and more particularly, to a connecting device capable ofachieving moving horizontally and rotating, an electronic equipmenthaving the connecting device, and a screen-detachable notebook computer.

Portable consumer electronic products such as notebook computers, mobilephones, video cameras, etc. fall into a category of product which isclosely related to human's daily life. As technology advances with thetimes, consumers pay more and more attention to appearances of theproducts while concerning about their performance. For example, a thinand compact design pleases human aesthetically, brings good portability,and thus is very popular among consumers.

In such electrical products, a connection rotating shaft is a veryimportant component, which makes a great impact on the product form,especially imposes considerable restrictions on appearance design. Takenotebook computer as an example: two portions of a conventionalconnection rotating shaft which rotate around the axis are respectivelyfixed to a base and a display screen, which remain unchanged withrespect to the position of the axis, so that the products present onlyone single form. What's more, a current trend is that the notebookcomputers are designed to be thinner and thinner, and the conventionalconnection rotating shaft imposes some restrictions in this regard. Bothproduct form and appearance design have higher demand for connectionrotating shaft.

Therefore, a connecting device is required to reduce restrictions on theproduct form and the appearance design.

Moreover, good portability is one of selling points of notebookcomputers, so while the notebook computers are improved in performance,to be thinner and lighter is always a trend of their development.

Along with a development of the semiconductor technology related tostorage, and touch screen etc., tablet personal computers are gettingmore and more popular in recent years. Tablet personal computer takes atouch screen as an input device, which makes the keyboard omitted, andintegrates the processor, storage, main board and display into onepanel, resulting in a better portability. However, due to restrictionsin terms of dimension, thermal dissipation etc., the performance oftablet computers is inevitably limited to some extent.

Accordingly, a novel notebook computer, which combines the conventionalnotebook computer and tablet computers, has been developed, namely,split-type notebook computers, or referred to as a screen-detachablenotebook computer. This type of notebook computers can be used not onlyas conventional notebook computers, but also as tablet computersdirectly with the screen detached, which enables this type of notebookcomputers have advantages of both the conventional notebook computer andthe tablet computer.

For example, FIG. 11 illustrates a screen-detachable notebook computer,which includes a base part 1 and a screen part 2 connected to each otherby a hinge part 3, and the screen part 2 being detachable from the hingepart 3. However, as shown in FIG. 1, after the screen part 2 is detachedfrom the hinge part 3, the hinge part 3 is protruding on the base part1. Therefore, the remaining base part 1 and the hinge part 3 are noteasy to handle or carry due to their irregular shapes.

Therefore, a novel screen-detachable notebook computer needs to bedesigned, which can overcome one or more of the above problems and otherproblems.

In thefollowing description, detailed information of the common technology isomitted to avoid unnecessary misunderstanding of the disclosure. Thesame or similar reference signs in different drawings identify the sameor similar elements.

First Exemplary Embodiment

FIG. 1 is a perspective diagram illustrating a connecting device 100according to the first exemplary embodiment of the present disclosure;FIG. 2 is a disassembling perspective diagram illustrating respectiveelements included in the connecting device 100 according to the firstexemplary embodiment of the present disclosure.

Referring to FIG. 1 and FIG. 2, the connecting device 100 according tothe first exemplary embodiment of the present disclosure includes afirst fixed component 10, a mobile component 20, a rotational component30 and a second fixed component 40.

The first fixed component 10 can be a sliding base, which can be fixedto other components to be connected by the connecting device 100. In anexample, the first fixed component 10 can have a through hole forconnecting other components by screws. Alternatively, the first fixedcomponent 10 can be connected to other components in other manners suchas welding, riveting, splicing and so on.

The mobile component 20 can include: two sliding components capable ofmoving horizontally with respect to each other, e.g., sliding; and alimit component for limiting a distance within which the two slidingcomponents move horizontally with respect to each other. In the presentembodiment, as shown in the drawings, the first sliding component can bea sliding cavity 22 formed in the first fixed component 10. The slidingcavity 22 can have a predetermined shape, for example, but not limitedto a rectangle having a chamfer. The second sliding component can be asliding body 21. A first end of the sliding body 21 can be held in thesliding cavity 22 of the first fixed component 10, and its second endcan be located outside the sliding cavity 22. The sliding body 21 canhave a predetermined shape, for example, a shape fitting the slidingcavity 22. In this way, the sliding cavity 22 and the sliding body 21 ofthe first fixed component 10 cooperate with each other, so that thesliding body 21 can perform one-dimensional linear movement inside thesliding cavity 22 in a moving direction same as an extension directionbetween the first end and second end of the sliding body 21.

In this embodiment, the limit component of the mobile component 20 canbe formed as follows. As shown in FIG. 1 and FIG. 2, the sliding body 21can have an opening 23 formed therein, a stopper 11 can run through theopening 23 and can be fixed to the first fixed component 10, so as tolimit one end of the sliding body 21 inside the sliding cavity 22.

Optionally, the connecting device 100 can also include an elasticcomponent, to provide elastic force for pressing the mobile component 20toward the first fixed component 10. In this embodiment, as shown inFIG. 1 and FIG. 2, the elastic component can be a first elasticcomponent 12 mounted inside the opening 23. The elastic component 12 canbe a spring (as shown in the drawings) or any other elastic items likeelastic rubber and so on. The elastic component 12 can have one endleaning against a side wall of the opening 23, and the other end leaningagain the stopper 11, so as to provide elastic force for pressing thesliding body 21 into the sliding cavity 22. It can be understood thatwhen external force is applied, the elastic force of the elasticcomponent 12 can be overcome to pull the sliding body 21 to move outwardhorizontally.

The rotational component 30 can be connected to the mobile component 20,so as to move horizontally with respect to the first fixed component bythe mobile component 20. In the embodiment, the rotational component 30can be, for example, a rotating shaft. The rotating shaft generallyincludes a core shaft, a shaft housing and two fixing plates. The twofixing plates are respectively fixed onto (or are integrally formedwith) the core shaft and shaft housing. The shaft housing can be bushedaround the core shaft to rotate. The rotating shaft also can include twoshaft housings, which both houses the core shaft and respectively arefixed onto the two fixing plates to achieve rotating.

In this embodiment, as shown in FIG. 1 and FIG. 2, the rotationalcomponent 30 includes a core shaft 32 and the shaft housing 31. Thesliding body 21 and the second fixed component 40 can be used as theabove-mentioned two fixing plates. In the embodiment as shown in thedrawings, the core shaft 32 can extend from the end of the sliding body21 outside the sliding cavity, and the shaft housing 31 is formedintegrally with the second fixed component 40. The core shaft 32 extendsin a direction different from a sliding direction of the sliding body21. Preferably, the core shaft 32 extends in a direction substantivelyvertical to the sliding direction of the sliding body 21, but thepresent disclosure is not limited thereto, the extension direction ofthe core shaft 32 and the sliding direction of the sliding body 21 canalso form any other angle.

In another embodiment not shown, the core shaft 32 can extend from aside of the second fixed component 40, and the shaft housing 31 can beformed integrally at the second end of the sliding body 21.

In yet another embodiment now shown, the rotational component caninclude two shaft housings. One shaft housing is formed integrally withthe second fixed component 40 (as shown in FIGS. 1-2), and the other isformed at the second end of the sliding body 21. The core shaft 32 canbe inserted into two shaft housings.

In each embodiment, the shaft housings and the core shaft can bedesigned in a similar way as the conventional rotating shaft. Forexample, friction plates are set in the shaft housings to make therotating shaft more compact. No more description is repeated here.

As shown in FIGS. 1-2, the second fixed component 40 is fixed to (or isformed integrally with) the shaft housing 31, to rotate with respect tothe first fixed component 10 by the rotational component 30, and movehorizontally with respect to the first fixed component 10 by the mobilecomponent 20. The second fixed component 40 can have a through hole forconnecting to other component by screws. Alternatively, the second fixedcomponent 40 can be connected to other components in other manners suchas welding, riveting, splicing and so on.

In a variation (not shown) of the first embodiment, the opening 23 canbe an un-closed opening, i.e., groove, formed on one side or two sidesof the sliding body 21. The elastic component, for example, the firstelastic component 12 has one end leaning against the side wall of theopening 23, and the other end leaning against the stopper 11 which runsthrough the opening 23, so that elastic force is provided to press thesliding body 21 into the sliding cavity 22.

In another variation (not shown), the sliding body 21 can have bulgesformed on one side or two sides thereof. There is a flange which coverspart of the sliding cavity 22 at the opening of the sliding cavity22(refer to FIG. 4 for the similar). The second elastic component 12being an elastic component has one end leaning against the bulges of thesliding body 21, and the other end leaning against the flange at theopening of the sliding cavity 22, to provide elastic force for pressingthe sliding body into the sliding cavity 22.

As stated above, in the rotating shaft 100 according to the firstexemplary embodiment, the first fixed component 10 can move horizontallyand rotate with respect to the second fixed component 40 by the mobilecomponent 20 and the rotational component 30.

Second Exemplary Embodiment

FIG. 3 is a perspective diagram illustrating a connecting device 200according to the second exemplary embodiment of the present disclosure.The second exemplary embodiment shown in FIG. 3 is basically the same asthe exemplary embodiments shown in FIG. 1 and FIG. 2, except that theconnecting device 200 does not include an elastic component. Since thecomponents included in the connecting device 200 in the second exemplaryembodiment are the same as those in the first exemplary embodiment, nomore descriptions will be repeated here.

The first and second exemplary embodiments are compared as follows. Inthe first exemplary embodiment, the connecting device 100 includeselastic components, e.g., the first and second elastic components 12,which provide elastic force for press the sliding body into the slidingcavity 22. However, the second exemplary embodiment does not include anyelastic component. In this case, an external force can be applied tomake the sliding body 21 restored to its initial position inside thesliding cavity 22. For example, the sliding body 21 can be returned intothe sliding cavity manually.

It can be understood that in the embodiments disclosed above andhereinafter, the elastic component, if any, can be omitted, andalternatively, the mobile component can be restored to the initialposition manually.

Third Exemplary Embodiment

FIG. 4 is a cross-sectional diagram illustrating a connecting device 300according to the third exemplary embodiment of the present disclosure.It should be noted that FIG. 4 only shows a first fixed component 10′and part of a mobile component, and the other components can be the sameas those in the first and second exemplary embodiments, which thus arenot shown. And no more descriptions of the same or similar componentswill be repeated here.

As shown in FIG. 4, a first sliding component can be a sliding cavityformed on the first fixed component 10′. A flange can be formed at theopening of the sliding cavity to cover part of the sliding cavity. Thus,an opening area of the sliding cavity is less than its internal area.

The second sliding component can include a pull rod 25 and a piston 24,the piston 24 being formed at a first end of the pull rod 25 and locatedinside the sliding cavity. The side of the piston 24 and an inner wallof the sliding cavity are airtight sealed, the side of the pull rod 25and the flange at the opening of the sliding cavity are airtight sealed,and the pull rod 25 can pull the piston 24 to perform one-dimensionallinear movement inside the sliding cavity. The sliding cavity in anouter side of the piston 24 can be sealed with compressed air of highdensity, and the sliding cavity in an inner side of the piston 24 can bevacuum or is sealed with air of low density. Thus, the compressed air ofhigh density sealed in the sliding cavity outside the piston 24 can forma third elastic component, which can provide elastic force for pressingthe second sliding component into the sliding cavity. When externalforce is applied, the elastic force of the compressed air can beovercome to pull the second sliding component to slide outwards.

It can be understood that in a variation of the third exemplaryembodiment, the compressed gas of high density can be replaced with anelastic component. In such a case, it is not necessary that the secondsliding component and the first fixed component 10′ are airtight sealed.

Fourth Exemplary Embodiment

FIG. 5 is a diagram illustrating a connecting device 400 according tothe fourth exemplary embodiment of the present disclosure; FIG. 6 is adiagram of side view of the mobile component 20 of the connecting device400 shown in FIG. 5. It should be noted that FIG. 5 only shows part ofthe components of the connecting device 400. It can be understood thatthe other components can be similar to or same as those in the first tothird exemplary embodiments. And no more descriptions of the same orsimilar components will be repeated here.

As shown in FIGS. 5 and 6, the first sliding component can be two guiderails 26 extending in parallel in a same direction on two opposite sidesof a first fixed component 10″ respectively. Each of the guide rails 26can form a guide groove. The second sliding component, e.g., two bulges,can be provided in two grooves. Both ends of the core shaft 32 can beconnected to the two bulges respectively. Alternatively, the core shaft32 can be formed integrally with the bulges. The shaft housing (notshown) can be bushed around the core shaft 32.

In one example, the bulges can be, for example, a rectangle or square.Thus, the bulges are limited by the groove and cannot rotate, andfurther, the core shaft 32 fixed to or formed integrally with the bulgescannot rotate either, the shaft housing bushing around the core shaft 32can rotate. Friction plates can be set in the shaft housing to provideappropriate damping.

In another example, the bulges can be for example round, which is thesame as the core shaft 32. At this time, the core shaft 21 together withthe bulges can rotate with respect to the first fixed component 10″, andthe shaft housing can rotate with respect to the core shaft. At thistime, friction plates can be set on the inner wall of the groove and inthe shaft housing to provide the desired dumping.

In addition, as shown in the drawing, the elastic components, e.g., twofourth elastic components 12, can be mounted respectively in the groovesof the two guide rails 26 and is in an outer side of the bulge. In thisway, when an external force is not applied, the fourth elasticcomponents 12 can press the bulges and the core shaft 32 toward thefirst fixed component 10″; when an external force is applied, theelastic force can be overcome to pull the core shaft 32 together withthe bulges to move in a direction away from the first fixed component10″.

Fifth Exemplary Embodiment

FIG. 7 shows a notebook computer 500 according to the fifth exemplaryembodiment of the present disclosure; FIG. 8A and FIG. 8B are enlargedcross-sectional diagrams of a connection portion of the notebookcomputer 500 according to the fifth exemplary embodiment of the presentdisclosure, wherein FIG. 8A shows a closed state, and FIG. 8B shows anopen state.

As shown in FIG. 7, the notebook computer 500 includes a base portion510, a display portion 520, and a connecting device 530 for connectingthe base portion 510 and the display portion 520. The base portion 510can have, for example, a keyboard, a touch panel etc. The displayportion 520 can include, for example, a liquid crystal display screen.The connecting device 530 can include any connecting device according tothe aforesaid embodiments and other embodiments. Thus, the displayportion 520 can move horizontally and rotate with respect to the baseportion 510 by the connecting device 530.

Now, take the connecting device 100 according to the first exemplaryembodiment as an example, the connection between the rotating shaft 530and the base portion 510/the display portion 520 will be described indetails.

As shown in FIGS. 8A-8B, a flange portion 521 is formed on one side ofthe display portion 520. The flange portion 521 can be formed along thetotal length of the display portion 520 or at least part of the totallength. In a closed state, the flange portion 521 can cover at leastpart of the corresponding side of the base portion 510. The first fixedcomponent 10 of the connecting device 530 is connected to this side ofthe base portion 510. The second fixed component 40 (not shown in FIGS.8A-8B) is connected to the flange portion 521 of the display portion520. It can be understood that in another exemplary embodiment, thefirst fixed component 10 of the connecting device 530 can be formedintegrally with the base portion 510, and the second fixed component 40can be formed integrally with the display portion 520.

As shown in FIG. 8A, the flange portion 521 of the display portion 520can have a relatively high thickness, and in the closed state, theflange portion 521 covers at least part of the side of the base portion510. The relatively thick flange portion 521 can be securely mounted onthe connecting device 530, while the remaining of the display portion520 can have a relatively low thickness. Thus, the notebook computer 500according to the fifth exemplary embodiment of the present disclosurecan feature an even thinner design in general.

As shown in FIG. 7 and FIG. 8B (FIG. 9 can also be referred to), whenthe display portion 520 is opened, the flange portion 521 and acorresponding side of the base portion 510 of the display portion 520can form together a cam pair. Therefore, while the display portion 520rotates around the core shaft 32, it also pulls the sliding body 21 toovercome the elastic force and move in a direction away from the baseportion 510. When the display portion 520 is closed, the sliding body 21and the core shaft 32 move towards the base portion 510 with elasticforce functioned, and the flange portion 521 covers at least part of thecorresponding side of the base portion 510. Therefore, the notebookcomputer 500 looks quite compact and neat.

It can be understood that the base portion 510 and the display portion530 of the notebook computer 500 can be connected in a wired manner,e.g., connected with flexible cable, or in a wireless manner, e.g., viaBluetooth, to transmit signals.

As described above, the connecting device in the present disclosure maynot include an elastic component, e.g., the elastic component 12 asshown in FIGS. 8A-8B. In such a case, the sliding body 21 and the coreshaft 32 can be restored to the initial position manually. Theconnecting device can also be linked to a shackle on the opposite sideof the notebook computer. The notebook computer generally includes ashackle on the opposite side of the connecting device 530. When thenotebook computer is closed, the shackle locks up the display portionand the base portion, which prevents the display portion from beingopened with respect to the base portion unintentionally. When thedisplay portion needs to be opened up, an operating button of theshackle can be slid or pressed, and then the display portion can berotated to open. The connecting device of this disclosure can be linkedto the shackle. When the notebook computer is closed, the mobilecomponent is also fixed at the initial position by a clamping bolt. Whenthe notebook computer is opened, the operating button of the shackle canbe slid or pressed, to make the clamping bolt retract by linkage, sothat the display portion is rotated to open, and meanwhile the mobilecomponent is pulled back to move horizontally outwards.

It should be understood that, although the above description takes thenotebook computer as an example, the connecting device in the presentdisclosure can also be applied to other electronic equipments such asmobile phone, camera and so on.

In addition, although several exemplary embodiments of the presentdisclosure are described above, it can be understood that the presentdisclosure is not limited to the disclosed exemplary embodiments, andthose of skill in the art can make various changes in form and detailswithin the spirit and scope of the present disclosure. For example, thefirst fixed component 10 and the mobile component 20 can form astructure similar to a structure of trail-type spring.

FIG. 12 illustrates a disassembling perspective diagram of ascreen-detachable notebook computer 2100 according to an exemplaryembodiment of the present disclosure; FIG. 13A is a diagram of side viewof the screen-detachable notebook computer 2100 in a closed state afterbeing assembled; FIG. 13B is a perspective diagram of thescreen-detachable notebook computer 2100 in an open state after beingassembled.

As shown in FIG. 12, the screen-detachable notebook computer 2100according to an exemplary embodiment of the present disclosure caninclude a base part 210, a middleware 230 and a display part 240. Themiddleware 230 can be connected to the base part 210 by a rotating shaftpart 220, and the display part 240 can be detachably mounted onto themiddleware 230, so that the display part 240 together with themiddleware 230 can be opened and closed with respect to the base part210 by the rotating shaft part 220. In a closed state, as shown in FIG.13A, the middleware 230 can cover the same side of the base part 210 andthe display part 240. Preferably, the middleware 230 can have anapproximately rectangular cross section, but the present disclosure isnot limited thereto. In a direction substantively vertical to thesurface where the base part 210 and the display part 240 are located(i.e., in the direction of thickness), a first size of the middleware230 can be substantially equal to a sum of thicknesses of the base part210 and the display part 230 on the same sides. The “substantially equalto” here is given considering that there might be a certain gap betweenthe base part 210 and the display part 230. That is to say, in theclosed state, the middleware 230 can completely cover this side of thebase part 210 and the display part 240.

The display part 240 and the middleware 230 can rotate to open withrespect to the base part 210 by the rotating shaft part 220. Whenrotated in a predetermined angle, as shown in FIG. 13B, an upper surfaceof the middleware 230 is substantively coplanar with an upper surface ofthe base portion 210. In a preferred embodiment that the middleware 230has a rectangular cross section, the predetermined angle can be 90°. Itshould be understood that, the screen-detachable notebook computeraccording to the exemplary embodiment of the present disclosure canrotate in various angles greater than or less than the predeterminedangle during application, which shall be illustrated later in detailtogether with the rotating shaft part 220.

As described above, the display part 240 can be detached from themiddleware 230. The detached display part 240 can be used as a displaypart of other device, or can be used independently as a tablet computer.FIG. 14 shows the base part 210 and the middleware 230 rotated in apredetermined angle after the display part 240 is detached. As shown inFIG. 14, the upper surface of the middleware 230 is substantivelycoplanar with the upper surface of the base portion 210. In this way,bulges on the surface of the base part 210 are eliminated; themiddleware 230 and the base part 210 present a regular stand-alone wholein appearance, for better mobility and portability. In an exemplaryembodiment, a second size of the middleware 230 in a direction verticalto the upper surface can be substantially equal to the thickness of thebase part 210 on the side. Thus, the middleware 230 can be taken as anextension of the base part 210 to further enhance the visual integrity.

FIG. 15 shows a structural example of the middleware 230. As shown inFIG. 15, the middleware 230 can have a groove 231 formed therein, thedisplay part 240 can be inserted into the groove 231, and the edge ofthe display part 240 can be held by the side wall of the groove 231. Inthis way, when rotating, the edge of the display part 240 and the sidewall of the groove 231 shall bear even force, to avoid connection damagebetween the two.

Referring further to FIG. 15, a buckle structure 232 can be provided inthe groove 231, a snap hole or slot structure (not shown) correspondingto the buckle structure 232 can be formed on a corresponding edge of thedisplay part 240. When the display part 40 is inserted into the groove231, the buckle structure 232 can stick onto the display part 240 by thesnap hole or slot structure on the display part 240. In this way, thedisplay part 240 can be fixed inside the groove 231.

In addition, the middleware 230 also can be provided with a button 233linked to the buckle structure 232. When the button 233 is pressed down,the buckle structure 232 loosens to release the display part 240, sothat the display part 240 can be detached from the middleware 230. Thebuckle structure 232, snap hole or slot structure (not shown), and thebutton 233 are structures well known for those of skill in the art, canbe realized in various manners, and are not limited to the shapes shownin the drawings. Therefore, a detailed description of these componentsis omitted here.

Alternatively but not necessarily, as shown in FIG. 15, one or moreelastic components 234 can also be provided in the groove 231 of themiddleware 230. When the display part 240 is being mounted, the elasticforce of the elastic component 234 needs to be overcome to press thedisplay part 240 into the groove 231; when the display part 240 is beingdetached, only the button 233 needs to be pressed down, then the elasticcomponent 234 can eject the display part 240 outwards. Thus, the closefitting between the display part 240 and the groove 231 can be enhanced;the detaching of the display part 240 is facilitated also. In anexemplary embodiment, the elastic component 234 can be, for example, aspring, which is thin in thickness to save the space for the displaypart 240 to be inserted.

An electrical connector 235 can also be provided in the groove 231 ofthe middleware 230, and the electrical connector 235 can be connected tothe base part 210 via a flexible cable (not shown). When the displaypart 240 is inserted into the groove 231, the electrical connector 235can be inserted into an interface of the edge of the display part 240,so that the display part 240 can be electrically connected to the basepart 210. It can be appreciated that the display part 240 also can beelectrically connected to the base part 210 in a wireless manner, e.g.,via Bluetooth etc.

In an exemplary embodiment, the middleware 230 can further have a coverplate 236 (refer to FIG. 14) in the groove 231. The cover plate 236 canbe supported by the elastic component 233 to cover an opening of thegroove 231. In this way, after the display part 240 is detached, it canprevent the groove 231 from being exposed, so as to improve integrity ofthe middleware 230 and the base part 210. The cover plate 236 can havean opening, so that when the cover plate 236 is pressed down, thecomponents in the groove 231 such as the buckle structure 232 and theelectrical connector 234 can be exposed, and thus the mounting of thedisplay part 240 shall not be affected. A limit component (not shown)can be provided at the opening of the groove 231 to limit the coverplate 236 inside the groove 231, i.e., the cover plate 236 is preventedfrom being ejected out of the groove 231 by the elastic component 233.

Returning to FIG. 13A, the middleware 230 can have a rectangular crosssection, which contributes to integrity of the components whendisassembled and assembled. However, when the middleware 230 is rotatedwith respect to the base part 210, the rectangular corner may collidewith the side of the base part 110, and thus the rotation is blocked.

Therefore, according to an exemplary embodiment of the presentdisclosure, the rotating shaft part 220 not only can rotate, but alsocan move horizontally.

FIG. 16 is a perspective diagram of assembly of the rotating shaft part220 according to an exemplary embodiment of the present disclosure; FIG.17 is a perspective diagram of disassembly of the rotating shaft part220.

Referring to FIG. 16 and FIG. 17, the rotating shaft part 220 accordingto an exemplary embodiment of the present disclosure includes a firstfixed component 221, a mobile component 222, a rotational component 223and a second fixed component 224.

The first fixed component 221 can be a sliding base, which can be fixedto one of the base part 210 and the middleware 230, and the second fixedcomponent 224 can be fixed to the other of the base part 210 and themiddleware 230. For convenience, the following description is given bytaking the first fixed component 221 being fixed to the base part 210and the second fixed component 224 being fixed to the middleware 230 asan example. In an example, the first fixed component 221 can have athrough hole for connecting to the base part 210 by screws.Alternatively, the first fixed component 221 can be connected to thebase part 210 in other manners such as welding, riveting, splicing andso on. Or, the first fixed component 221 can be formed integrally withthe base part 210.

The mobile component 222 can include: two sliding components capable ofmoving horizontally with respect to each other, e.g., sliding; and alimit component for limiting the distance within which the two slidingcomponents move horizontally with respect to each other. In the presentembodiment, as shown in the drawings, the first sliding component can bea sliding cavity 225 formed in the first fixed component 221. Thesliding cavity 225 can have a predetermined shape, for example, but notlimited to a rectangle having a chamfer. The second sliding componentcan be a sliding body 226. A first end of the sliding body 226 can beheld in the sliding cavity 225 of the first fixed component 221, and itssecond end can be located outside the sliding cavity 225. The slidingbody 226 can have a predetermined shape, for example, a shape fittingthe sliding cavity 225. In this way, the sliding cavity 225 and thesliding body 226 of the first fixed component 221 cooperate with eachother, so that the sliding body 226 can perform one-dimensional linearmovement inside the sliding cavity 225 in a moving direction the same asan extension direction between the first end and second end of thesliding body 226.

In this embodiment, the limit component of the mobile component 222 canbe formed in the following way. As shown in FIG. 16 and FIG. 17, thesliding body 226 can have an opening 227 formed therein, a stopper 228can run through the opening 227 and can be fixed to the first fixedcomponent 221, so that one end of the sliding body 226 is limited insidethe sliding cavity 225.

In thisembodiment, as shown in FIG. 16 and FIG. 17, the elastic component 229can be a spring or any other elastic items like elastic rubber and so onprovided in the opening 227. The elastic component 229 can have one endleaning against a side wall of the opening 227, and the other endleaning again the stopper 228, so that an elastic force is provided forpressing the sliding body 226 inside the sliding cavity 225. It can beunderstood that when external force is applied, the elastic force of theelastic component 229 can be overcome to pull the sliding body 226 tomove outward horizontally.

The rotational component 223 can be connected to the mobile component222, to move horizontally with respect to the first fixed component bythe mobile component 222. In the embodiment, the rotational component223 can be, for example, a rotating shaft. The rotating shaft generallyincludes a core shaft, a shaft housing and two fixing plates. The twofixing plates are respectively fixed onto (or are integrally formedwith) the core shaft and shaft housing. The shaft housing can be bushedaround the core shaft to rotate. The rotating shaft also can include twoshaft housings, both of which house the core shaft and are respectivelyfixed onto the two fixing plates to achieve rotating.

In this embodiment, as shown in FIG. 16 and FIG. 17, the rotationalcomponent 223 includes a core shaft 223 and the shaft housing 252. Thesliding body 226 and the second fixed component 224 can be used as theabove-mentioned two fixing plates. In the embodiment as shown in thedrawings, the core shaft 251 can extend from the end of the sliding body226 outside the sliding cavity, and the shaft housing 252 is formedintegrally with the second fixed component 224. The core shaft 251extends in a direction different from a sliding direction of the slidingbody 226. Preferably, the core shaft 251 extends in a directionsubstantively vertical to the sliding direction of the sliding body 226,but the present disclosure is not limited thereto, the extensiondirection of the core shaft 251 and the sliding direction of the slidingbody 26 can also form any other angle.

In another embodiment not shown, the core shaft 251 can extend from theside of the second fixed component 224, and the shaft housing 252 can beformed integrally at the second end of the sliding body 226.

In yet another embodiment now shown, the rotational component caninclude two shaft housings. One shaft housing is formed integrally withthe second fixed component 224 (as shown in FIGS. 16-17), and the otheris formed at the second end of the sliding body 226. The core shaft 251can be inserted into two shaft housings

In each embodiment, the shaft housings and the core shaft can bedesigned in a similar way as the conventional rotating shaft. Forexample, friction plates are set in the shaft housings to make therotating shaft more compact. No more description is repeated here.

As shown in FIGS. 16-17, the second fixed component 224 is fixed to (oris formed integrally with) the shaft housing 252, so as to rotate withrespect to the first fixed component 221 by the rotational component223, and move horizontally with respect to the first fixed component 221by the mobile component 222. The second fixed component 224 can have athrough hole for connecting to the middleware 230 by screws.Alternatively, the second fixed component 224 can be connected to themiddleware 230 in other manners such as welding, riveting, splicing andso on. Or, the second fixed component 224 can be formed integrally withthe middleware 230.

In a variation (not shown) of the above embodiment, the opening 227 canbe an un-closed opening, i.e., groove, formed on one side or two sidesof the sliding body 226. The elastic component 229 has one end leaningagainst the side wall of the opening 227, and the other end leaningagainst the stopper 228 which runs through the opening 227, so that anelastic force is provided for pressing the sliding body 226 into thesliding cavity 225.

It should be noted that, under the teaching of the above disclosure,those of skill in the art can make various modifications to thestructure of the above components without departing from the spirit andscope of the present disclosure, and such modifications all fall intothe scope of the present disclosure defined by the attached claims.

As mentioned above, in the screen-detachable notebook computer 2100according to an exemplary embodiment of the present disclosure, therotating shaft part 220 not only can rotate, but also can movehorizontally. Thus, as shown in the cross-sectional diagram of therotating shaft part 220 in FIG. 18A, when the display part 240 drivesthe middleware 230 to rotate, a bottom corner of the middleware 230adjacent to the base part 210 and the edge of the base part 210 form acam pair, so that while rotating, the middleware 230 moves horizontallyaway from the base part 210. As shown in FIG. 18B, when rotating toabout 90°, the upper surface of the middleware 230 is substantivelycoplanar with the upper surface of the base part 210. Then, if rotatingcontinuously, a corner of the middleware 230 adjacent to the aforesaidbottom corner and the edge of the base part 210 form a cam pair, so thatwhile rotating, the middleware 230 moves horizontally away from the basepart 210. In conjunction with FIG. 15, it can be understood that theedge of the middleware 230 connected to the rotating shaft part 220 canbe formed to have a groove, so that while rotating, the edge of themiddleware 230 shall not collide with the sliding body 226 of therotating shaft part 220. The opening and closing processes are donebasically in symmetry, so there is no further description.

By using the rotating shaft part 220 of the exemplary embodiment, themiddleware 230 and the base part 210 can be mounted together in acompact and neat manner, without affecting relative rotation of the two.However, it should be appreciated that the present disclosure is notlimited to the aforesaid rotating shaft part which can not only rotatebut also move horizontally, but can also make use of a conventionalrotating shaft part which only provides rotating function. Then, themiddleware 230 can be mounted with a predetermined gap with respect tothe base part 210, and the lower edge of the middleware 230 (in theclosed state) can be rounded, without affecting the relative rotationbetween the middleware 230 and the base part 210.

In one example, the display part 240 can include a first hardware systemand a first system formed based on a first operating system of the firsthardware system. The base part 210 can serve as an extended portion ofthe first system, such as keyboard, touch panel, fingerprint reader,card reader and so on.

In another example, the base part 210 can include a second hardwaresystem and a second system formed based on a second operating system ofthe second hardware system. The display part 240 can serve as an outputdisplay portion of the second system.
